Amazon s3 S3失效后的政策文件是否依赖于存储桶？

我有直接的HTML发布到S3 bucket，用于bucket A。如果我保持所有代码完全相同，但替换并签署bucket B的策略，Amazon将返回InvalidPolicyDocument错误。bucket在接受已发布的对象之前是否需要启用或设置

提前谢谢！ 本

另外，我已经在策略和上传URL中更改了bucket名称

pps。根据请求，我在Fiddler中跟踪了这两个请求。以下是请求和响应：

好的要求是：

确保在操作URL和策略文档中都更改了bucket名称

更新

以下是这两种策略的Base64解码版本：

好

{
  'conditions': [
    {
      'bucket': '0wdz435hntscj306sxr2-test-bucket'
    },
    ['starts-with', '$key', 'uploads/'],
    ['starts-with', '$Filename', ''],
    {
      'acl': 'private'
    },
    {
      'success_action_status': '201'
    }
  ],
  'expiration': '2009-06-10T18:17:59Z'
}

{
  'conditions': [
    {
      'bucket': u'0wdz435hntscj306sxr2-m4lbeta'
    },
    ['starts-with', '$key', 'uploads/'],
    ['starts-with', '$Filename', ''],
    {
      'acl': 'private'
    },
    {
      'success_action_status': '201'
    },
    {
      'Content-Type': 'application/octet-stream'
    }
  ],
  'expiration': '2009-06-10T18:09:14Z'
}

坏的

{
  'conditions': [
    {
      'bucket': '0wdz435hntscj306sxr2-test-bucket'
    },
    ['starts-with', '$key', 'uploads/'],
    ['starts-with', '$Filename', ''],
    {
      'acl': 'private'
    },
    {
      'success_action_status': '201'
    }
  ],
  'expiration': '2009-06-10T18:17:59Z'
}

{
  'conditions': [
    {
      'bucket': u'0wdz435hntscj306sxr2-m4lbeta'
    },
    ['starts-with', '$key', 'uploads/'],
    ['starts-with', '$Filename', ''],

    {

}

不知何故，一个额外的“u”卡在了错误策略的存储桶行中

如果您使用一个“100%兼容”服务而不是原始S3，请检查策略中键的顺序，

过期

必须是第一位的（如中）。

您能使用Fiddler跟踪这两个请求并发布结果吗？谢谢Bryce！额外的u表示unicode字符串，这是使用Google应用程序引擎时默认的Python字符串类型。在对策略进行编码之前，我可能必须使用str（）将其转换为常规字符串。接得好！
